Airtac LSH Linear Guide Rail LSH25HN2X3400S20AH-M6
2. High Rigidity Four-Directional Equal Load Design: Incorporates 4-row ball circuits with 45° contact angle configuration, achieving optimal two-point contact for bidirectional radial/lateral load capacity. Optional preload application enhances system rigidity when required.
3. Interchangeability: Stringent manufacturing precision ensures dimensional consistency within stable tolerances. Integrated retainer design prevents ball dislodgement, enabling between and matching guideways while preserving operational smoothness, preload integrity, and motion accuracy.

Industrial-grade linear motion system featuring hardened steel construction with chromium-plated surfaces for corrosion resistance. The HN-series design incorporates optimized ball circuit geometry achieving ≤0.005mm/m running parallelism. Integrated sealing system protects against particulate contamination in harsh environments while maintaining smooth operation at speeds up to 5m/s.
- High-speed CNC gantry systems
- Automated warehouse stacker cranes
- Semiconductor wafer handling robots
- Precision optical inspection equipment
- Heavy-duty packaging machinery
- Medical CT scanner positioning systems
Installation note:
Requires mounting surface flatness ≤0.02mm/m and parallelism ≤0.03mm/m.
Use torque wrench for M6 screws (recommended 4.5-5.0Nm).
Avoid thermal expansion by allowing 0.5mm clearance per meter at >25℃ ambient.
